The value of x in the equation is 26.7
<h3>How to solve an equation?</h3>
0.75x + 1.5y = 40
−1.5x − 1.5y = −60
add both equation to eliminate y .
Therefore,
−1.5x + 0.75x = -0.75x
1.5y + (- 1.5y) = 0
40 + (-60) = -20
Hence,
-0.75x = - 20
divide both sides by -0.75
-0.75x / -0/75 = - 20 / -0.75
x = - 20 / -0.75
x = 26.6666666667
x = 26.7

The value of m which makes the equation true is; 8.2
<h3>How to solve one variable equations</h3>
The given equation is;
The value of m, for which the equation is true can be evaluated as follows;
m – 4.7 = 3.5
Add 4.7 to both sides of the equation to isolate m.
m - 4.7 + 4.7 = 3.5 + 4.7
m = 8.2
A one variable equation also known as linear equation is an equation in which one unknown variable is solved for.
Therefore, the value of m which makes the equation true is; 8.2
