Bookwork code: L91 悭 not allowed Look at the simultaneous equations below. (1) $x-2 y=15$ (2) $x-3=4 y$ a) Rearrange equation (2) to make $x$ the subject. b) Using your answer to part a), solve the simultaneous equations using substitution. < Back to task Watch video Answer $>$

Step 1 ：Rearrange equation (2) to make x the subject: \(x = 4y + 3\)

Step 2 ：Substitute the rearranged equation into equation (1): \((4y + 3) - 2y = 15\)

Step 3 ：Solve for y: \(2y = 12\) so \(y = 6\)

Step 4 ：Substitute the value of y back into the rearranged equation to find the value of x: \(x = 4(6) + 3\)

Step 5 ：\(x = 27\)

Step 6 ：\(\boxed{x = 27, y = 6}\)
