Step-by-step explanation:
you need to substitute the x in (7x +2y=13) with (x=2y+11) to solve it
Answer:
A) x = 6
Step-by-step explanation:
4x - 2x + 6 = x + 12
Combine like terms
2x +6 = x+12
Subtract 6 from each side
2x+6-6 = x+12-6
2x = x+6
subtract x
2x-x = x+6-x
x = 6
1/4 squared would be 1/4 times 1/4 which would eqaul 0.063
Step-by-step explanation:
problem → 2^x = 4, solve for x
⇒2^x=4
⇒2^x=2^2
⇒x=2
