4(a + 10) = 80 find a

x = 4

Step-by-step explanation: To solve this equation, we start by distributing the 4 through the parentheses on the left side.

So we have 4(a) which is 4a and 4(10) which is 40.

So our equation now reads 4a + 40 = 80.

Solving from here, we subtract 40 from both sides of the equation and we have 4a = 40 and dividing both sides by 4, we find that x = 4.
