The answer is x = 5. There is nothing to evaluate there!

2x - 3y -7y + 4x - 5 = 6x - 10y - 5 and (6 x 10) - (10 x 4 ) - 5 = 60 - 40 - 5 = 15
You substitute 5 for x and 2 for y:4(5)-3(2)Now solve:4*(5)=203*(2)=620-6=14Anyone can do this, I'm 12 years old and answering this question!

explain how to evaluate an algebraic expression for given variables. how would we evaluate the expression "3x-4y+9" when x=2and y=5?
Interpreting the question as "evaluate f(x) = -x2 + 5 for x = 4". This is the same as asking "what is f(4)". To evaluate f(4) just replace each instance of the x in the definition of f(x) by the number 4: f(4) = -42 + 5. The result is -11.
(7 x 7) - (5 x 3)

(3 * 3)(2 * 5) (9)(10) 90
-1/3,1/3and 5/3
8+6x = ? 8+6*5 = ? 8+30 = ?
x = -2
0.5*8=.40
