The product of seven and a number squared.
Remember BIDMAS or however you learned it and that indices would be calculated before being multiplied by the term in front
Answer:
x =-7. .y=6
Step-by-step explanation:
3x + 2y = -9
(X – Y = -13)×3
3x + 2y = -9
3x – 3y = -39
5y = 30
y=6
3x +2(6)=-9
3x=-21
x=-7
When you want to find the value of a variable, isolate it.
First, add 355 to both sides of the equation to get rid of the -355 on the left side of the equation. We get -n = -602.
We're not done yet! We need to change the -n to +n, or just n. Multiply both sides by -1. We get n = 602.
n = 602.
Hope that helped you.
