3/2+2x/5=7/10

We simplify the equation to the form, which is simple to understand
3/2+2x/5=7/10

Simplifying:
+1.5+2x/5=7/10

Simplifying:
+1.5 + 0.4x=7/10

Simplifying:
+1.5 + 0.4x=0.7

We move all terms containing x to the left and all other terms to the right.
 + 0.4x=0.7-1.5

We simplify left and right side of the equation.
 + 0.4x=-0.8

We divide both sides of the equation by 0.4 to get x.
x=-2

The value of that fraction depends on the value of 'x'. Whatever 'x' happens
to be at the moment, the fraction is equal to about 61.1% of it. And if 'x' ever
changes, then the value of the fraction also changes, immediately.

Answer:

Step-by-step explanation:

Given the 2 equations

x = 3 - y → (1)

5x - 12 = y → (2)

Substitute x = 3 - y into (2)

5(3 - y) - 12 = y ← distribute and simplify left side

15 - 5y - 12 = y
