How do you solve and check your solution given #4.7=a+7.1#?

Answer 1

Savannah Anderson

#a=-2.4#

Verify by changing #a=-2.4# to #4.7=a+7.1#. This provides us with

#4.7=-2.4+7.1#

and #7.1-2.4=4.7

#4.7=4.7#

The response is accurate.

To solve for ( a ), you need to isolate it by subtracting 7.1 from both sides of the equation. This gives you ( a = 4.7 - 7.1 ), which simplifies to ( a = -2.4 ). To check your solution, substitute ( a = -2.4 ) back into the original equation: ( 4.7 = -2.4 + 7.1 ). When you simplify this, you should get ( 4.7 = 4.7 ), confirming that the solution is correct.
