A value that makes an equation true

(a)  

When an equation is rearranged so that a variable is alone on one side of the equal sign is an

(a)  

When we add the same number to both sides of an equation, then the two sides remain equal

y - 12 = 30

y -12 + 12 = 30 +12

When we divide the same number by both sides of an equation, then the two sides remain equal 7n=28 7n $$\div$$  7 = 28  $$\div$$  7

When we multiply the same number to both sides of an equation then the two sides remain equal

$$\frac{y}{7}=7$$ $$y\cdot$$  7 = 7 $$\cdot$$  7 

When we subtract the same number on both sides of an equation, then the two sides remain equal

y + 12 = 30

y + 12 - 12 = 30 -12
