Question

Please help need answer fast !!

Answer 1

Explanation:

(18x-8) + (11x) = 20x + 19

18x-8+11x=20x+19 remove parenthesis

29x-8=20x+19 combine like terms

29x=20x+27 subtract

9x=27 isolate the variable

x= 3

SU=20x+19

SU= 20(3)+19

SU= (60)+19

SU= 79

Answer 2

79

Explanation:

equation:

18x - 8 + 11x = 20x +19

Add like terms:

29x - 8 = 20x + 19

add 8 to both sides:

29x = 20x + 27

subtract 20x from btoh side:

9x = 27

Divide both sides by 9:

x = 3

substitute x into the equation for SU

SU = 20(3) + 19

Solve:

SU = 79
