The substitution method means you replace the variable in one equation with the other equation, so your new equation is x+4x-8=10. Add 10 to both sides to get 5x=18. Divide both sides by 5 to get x=3.6. This is a weird equation, but then to get y, work backwords. 3.6 times 2=7.2. 7.2-4=3.2 y=3.2. Finally to finish checking solve the equation as normal. 3.6+6.4=10. I hope this helped! Please give brainliest!
Your final answer is x=3.6 y=3.2
Here you go, i added a bit of explanation as to why i used the numbers to help you understand the method :)
The answer for ''4x = 5x - 12'' would be x = 12.
4x - 5x = 12 (subtract 5x from both sides)
-x = -12 (simplify 4x - 5x to -x)
x = -12 ( multiply both sides by -1) .
For the 2nd one ''10p + 5 = 18p - 6/2''
The answer is 1 not those choices
10p + 5 = 18p - 3
5 = 18p - 3 - 10p
5 = 8p - 3
5 + 3 = 8p
8 = 8p
1 = p
p = 1.
