Answer:
Step-by-step explanation:
So we have the system of equations:
And we want to multiply the first equation by some constant such that the resulting equation matches the coefficient of [x] in the second equation.
We can see that the coefficient of x in the second equation is 15.
So, to match 15, we must multiply the first equation by 3. So:
Multiply:
And we're done!
7. q+18 =22
q+18-18 =22-18 , q=4
at the problem q+18-18=22+18 mistake (should be subtracted from both sides)
8. r+10-10=22-10 r=12
r-15+15=5+15 r=20
r-18+18=14 +18 r=32
r+5-5=15-5 r=10
