Question

translate and solve. the product of seven and the difference between a number times negative two and two is negative forty two

Answer 1

We have product of 7, and "difference between a number times two, and two" equals -42. Rewrite this as an equation, and let a be the unknown number:
\[7 \times [(a \times -2) - 2] = -42\]
divide by 7 on both sides:
\[(a \times -2) - 2 = -6]\
add 2 two both sides:
\[a \times -2 = -4]\
finally divide by -2 on both times to isolate a
\[a = 2]\

Answer 2

We have product of 7, and "difference between a number times two, and two" equals -42. Rewrite this as an equation, and let a be the unknown number:
\[7 \times [(a \times -2) - 2] = -42\]
divide by 7 on both sides:
\[(a \times -2) - 2 = -42\]
add 2 to both sides:

Answer 3

(continued)
\[a \times -2 = -4\]
finally, divide by -2 on both sides to get a:
\[a = 2\]
