Step-by-step explanation:
<u>Step 1: Define</u>
-9x + 1 = -x + 17
<u>Step 2: Solve for </u><em><u>x</u></em>
- Add 9x on both sides: 1 = 8x + 17
- Subtract 17 on both sides: -16 = 8x
- Divide 8 on both sides: -2 = x
- Rewrite: x = -2
y= -32
Step-by-step explanation:
step 1: from the first equation you will make X the subject of formula, the equation then becomes;
X= <u>4-y</u>
2
step 2: substitute X in the second equation, the equation then becomes 5 * <u>[</u><u>4-y</u><u>]</u> + 3y = -6
[ 2]
step 3: find the LCM and then cross multiply; <u>20-5y+6y</u> = -6
2
20+y = -12
y= -12-20
y= -32
