Answer:
22x - 14
Step-by-step explanation:
pretty sure its like this..
3(4x-3)+5(2x-1)
= 3×4x + 3×(-3) + 5×2x + 5×(-1)
= 12x + (-9) + 10x + (-5)
and according to the rules of multiplying negative by positive...
= 12x - 9 + 10x - 5
combine like terms using the symbols on its left
= 12x + 10x - 9 - 5
= 22x - 14
Answer:
x = 1
Step-by-step explanation:
Expand brackets
2x + 16 - 4x = 10x + 4
Rearrange so that x's are on one side and whole numbers are on the other
2x - 4x - 10x = 4 - 16
Simplify
-12x = -12
Make x on its own
x = 1
5*(60+3)
You should write 63 in this way 60+3
