<h3><u>
The equation is true.</u></h3>
10x + 5 = 8x + 2
<em><u>Subtract 5 from both sides.</u></em>
10x = 8x - 3
<em><u>Subtract 8x from both sides.</u></em>
2x = -3
<em><u>Subtract both sides by 2.</u></em>
x = -1.5
Because we are able to get a value for x, we know that the equation is true, as we can plug the value of x back into the original equation to verify.
10(-1.5) + 5 = 8(-1.5) + 2
-15 + 5 = -12 + 2
-10 = -10 √ this equation is true.
Answer:
you is kinda slow if you don't know that my guy yeah and thank you for my points i will love to help but i am kinda just read this and now bye i will take my points bye
Step-by-step explanation:
bye stay smart my friend
X + 2y = 11
2x + y = 31
x = 11 - 2y
2(11 - 2y) + y = 31
22 - 4y + y = 31
3y = - 9
y = - 3
x = 11 - 2(-3)
x = 11 + 6
x = 17
