<span> 4.1 </span> A product of several terms equals zero.<span>
</span>When a product of two or more terms equals zero, then at least one of the terms must be zero.<span>
</span>We shall now solve each term = 0 separately<span>
</span>In other words, we are going to solve as many equations as there are terms in the product<span>

</span>Multiply both sides of the equation by (-1) : y = 0
Answer:
Let's solve your equation step-by-step.
−3.1x+7−7.4x=1.5x−6(x−
3
2
)
Step 1: Simplify both sides of the equation.
−3.1x+7−7.4x=1.5x−6(x−
3
2
)
−3.1x+7+−7.4x=1.5x+(−6)(x)+(−6)(
−3
2
)(Distribute)
−3.1x+7+−7.4x=1.5x+−6x+9
(−3.1x+−7.4x)+(7)=(1.5x+−6x)+(9)(Combine Like Terms)
−10.5x+7=−4.5x+9
−10.5x+7=−4.5x+9
Step 2: Add 4.5x to both sides.
−10.5x+7+4.5x=−4.5x+9+4.5x
−6x+7=9
Step 3: Subtract 7 from both sides.
−6x+7−7=9−7
−6x=2
Step 4: Divide both sides by -6.
−6x. /−6
=
2/−6
x=
−1/3
