Answer:
Step-by-step explanation:
The diagonals of a rectangle are equal.
2x + 10 = 56 That minus sign can't be there. Subtract 10 from both sides.
2x = 56 - 10 Combine
2x = 46 Divide by 2
x = 46/2
x = 23

Answer:
(3,1)
Step-by-step explanation:
The answer is <span>2(–4y + 13) – 3y = –29
Step 1: Express </span><span>x from the second equation
Step 2: Substitute x into the first equation:
The system of equations is:
</span><span>2x – 3y = –29
x + 4y = 13
Step 1:
</span>The second equation is: x + 4y = 13
Rearrange it to get x: x = - 4y + 13
Step 2:
The first equation is: 2x – 3y = –29
The second equation is: x = - 4y + 13
Substitute x from the second equation into the first one:
2(-4y + 13) - 3y = -29
Therefore, the second choice is correct.
