Question

$4x - 3y = 15 \\ 8x - 7y = 10$
​

Answer 1

Step-by-step explanation:

$4x - 3y = 15 \\ \\ x =( 15 + 3y) \div 4$

$we \: also \: got \: 8x - 7y = 10$

$substitute \: x \: value \: in \: 8x - 7y = 10$

$8(15 + 3y \div 4) - 7y = 10$

$120 + 24y \div 4 - 7y = 4$

$take \: lcm$

$120 + 24y - 28y = 16$

$120 - 4y = 16 \\ \\ - 4y = 16 - 120 \\ \\ 4y \: \: = 104 \\ \\ y \: \: \: \: = 104 \div 4 \\ \\ y \: \: \: \: = 26$

$therefore \: x = 15 + 3y \div 4 \\ \\ x= 15 + 3 \times 26 \div 4 \\ \\ x = 15 + 78\div 4 \\ \\ x = 93 \div 4$

$so \\ \\ x = 93 \div 4 \\ y = 26$

hope it helps!!
