You should plug the x and y values into the original equations to get your b value. You should get a b value of 7. Your new equation should be y=2x+7
1: Solve for either x or y in one of the equations. So x + y = -1 is y = -x -1
2: substitute the new equation in the opposite equation. So x - (-x - 1) = 7
3: distribute the negative. X + x + 1 = 7
4: combine like terms. 2x + 1 = 7
5: solve for x. Subtract 1 on both sides. 2x = 6
6: divide by 2 to get x by itself. X = 3
7: plug the new value of x into one of the ORIGINAL equations. 3 + y = -1
8: solve for y. Subtract 3 on both sides.
Y = -4
9: the solution is written as (x,y) so the solution would be (3, -4)
Answer:
63
Step-by-step explanation:
10 × 3 = 30
3× 11 = 33
30 + 33 = 63
Answer:
4 1/2 loads
Step-by-step explanation:
3/4 / 1/6 = 3/4 * 6 = 18/4 = 4 1/2
