Answer:
Step-by-step explanation:
3x+2y=7
Simplifying
3x + 2y = 7
Solving
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-2y' to each side of the equation.
3x + 2y + -2y = 7 + -2y
Combine like terms: 2y + -2y = 0
3x + 0 = 7 + -2y
3x = 7 + -2y
Divide each side by '3'.
x = 2.333333333 + -0.6666666667y

John is 10cm taller than Peter, if Peter is h than John's height would be h+10 since it is Peter's height plus ten.
x=1
2x+3=5
-3 -3
now the three gets canceled and 5-3 is 2
2x=2
now divide 2 on both sides
2x÷2=2÷2
