To evaluate the algebraic expression 7 + 5x for x = 10, you substitute the value of x into the expression. So, you get 7 + 5(10), which simplifies to 7 + 50. Therefore, the final answer is 57.
2x - 3y -7y + 4x - 5 = 6x - 10y - 5 and (6 x 10) - (10 x 4 ) - 5 = 60 - 40 - 5 = 15

explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
(7 x 7) - (5 x 3)
(3 * 3)(2 * 5) (9)(10) 90
Take 3 and substitute into the expression given to you but not mentioned in the question here and evaluate the expression. "Sub and Solve" I say.
x=y-8 z=x+12

15z = 15 x 6 = 90
There is no box below!
An number with a x after mean multiply, so it would be 4x12=48
2x - 3y -7y + 4x - 5 = 6x - 10y - 5 and (6 x 10) - (10 x 4 ) - 5 = 60 - 40 - 5 = 15
