Question

$table attributes columnalign right left right left right left right left right left right left columnspacing 0em 2em 0em 2em 0em 2em 0em 2em 0em 2em 0em end attributes row cell 2 x plus 3 y equals 1200 end cell row cell 3 x plus 2 y equals 1300 end cell end table$
Based on the system of equations above, what is the value of 5x 5y?

hint Hint:

Hint:

Linear equations in two variables is said to be an equation represented as ax+ by+ c = 0, where a, b, and c are referred to as the real numbers and the coefficient of x and y which means that a and b are unequal to 0. Equation that gives a straight line when plotted on the graph is known as a linear equation

The correct answer is: 5 x -5 y will be 2600

Explanation:

We have given a system of linear equation $table attributes columnalign right left right left right left right left right left right left columnspacing 0em 2em 0em 2em 0em 2em 0em 2em 0em 2em 0em end attributes row cell 2 x plus 3 y equals 1200 end cell row cell 3 x plus 2 y equals 1300 end cell end table$

We have to find the value of . $5 x plus 5 y$

Step 1 of1:
The given linear equation is $table attributes columnalign right left right left right left right left right left right left columnspacing 0em 2em 0em 2em 0em 2em 0em 2em 0em 2em 0em end attributes row cell 2 x plus 3 y equals 1200 end cell row cell 3 x plus 2 y equals 1300 end cell end table$

Add both the equation we will get

$table attributes columnalign right left right left right left right left right left right left columnspacing 0em 2em 0em 2em 0em 2em 0em 2em 0em 2em 0em end attributes row cell left parenthesis 3 x plus 2 x right parenthesis plus left parenthesis 3 y plus 2 y right parenthesis equals 2600 end cell row cell 5 x plus 5 y equals 2600 end cell end table$

Which is the desired result.

Final answer:
The value of 5x + 5y will be 2600
