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
