Answer:
x=-2
Step-by-step explanation:
You can substitute the first equation into the second:
-3x+3=5x+19
Add 3x on both sides:
3=8x+19
Subtract 19 on both sides:
-16=8x
Divide 8 on both sides:
x=-2
12 ^3 and 11^3 haven't got the same base so the rules of exponents do not apply.
Bases have to be the same:- for example 12^3 * 12*3 = 12 ^(3+3) = 12^6
Answer:
m=7
Step-by-step explanation:
9m=4m+35
move variable to the left
9m-4m=35
collect like terms
5m=35
divide both sides by 5
m=7
It's d. K' (-4, 6); L' (-3, 3) Hope I helped♡
