Answer:
x = 3, y = - 2
Step-by-step explanation:
By substitution method,
4x + y = 10 -------> equation 1.
7x + 2y = 17 -------> equation 2.
From equation 1,
y = 10 - 4x ------> equation 3.
Substitute equation 3 in 2,
7x + 2 ( 10 - 4x ) = 17
7x + 20 - 8x = 17
7x - 8x = 17 - 20
- x = - 3
x = 3
Substitute x = 3 in equation 1,
4 ( 3 ) + y = 10
12 + y = 10
y = 10 - 12
y = - 2
Hence,
x = 3
y = - 2
Answer:
x = 33.92.
Step-by-step explanation:
0.21 (3x + 3) + 4 = 26
Distribute the 0.21 over the parentheses:
0.63x + 0.63 = 22
0.63x = 22 - 0.63
0.63x = 21.37
x = 21.37 / 0.63
x = 33.92 (answer).
