How do you solve 8x plus 5x plus 9 equals 61?

Answer 1

first get the left hand side to only contain x's

this requires you to get rid of the 9 on the left hand side

so minus 9 on both sides of the equal sign

so 8x + 5x + 9 = 61 becomes 8x + 5x +9 -9 = 61 -9 which is 8x + 5x = 52

now add the x's

so 13x = 52

then divide both sides by 13 to find the value of x

x = 4
