Answer: x = -6</h2>
<h3>
Step-by-step explanation:</h3>
To solve for x, we have to find a way to make x the subject of the equation (get x on one side and everything else on the other side)
<h3>
</h3>
since -4 = (2/3)x [mutiply both sides by 3]
⇒ -4 × 3 = 2x [divide both sides by 2]
⇒ (-12/2) = x [simplify by dividing -12 by 2]
∴ x = -6

Answer:The first method, by substituting 5 into the expression (-2)x + 6 gives the coreect answer of -4
Step-by-step explanation:
Ist method
Substituting x = 5 into the expression (-2)x + 6, we have
(-2) 5 + 6,
=-10 + 6
=-4
2nd method
Substitute x = -1 into the expression (-2)x + 6,we have
(-2)(-1) + 6
2 +6=10
The first method, by substituting 5 into the expression (-2)x + 6 gives the coreect answer of -4
