Answer:
x = 1.23529
Step-by-step explanation:
Step 1: Write equation
3/17 = x/7
Step 2: Solve for <em>x</em>
- Cross multiply: 21 = 17x
- Divide both sides by 17: 21/17 = x
- Rewrite: x = 21/17
- Convert to decimal: x = 1.23529
For this case, what we are going to do is use the following property:
Multiply an equation by a scalar.
In this case, the scalar will be:
k = -2
We have then that equation 2 will be:
k * (4x + y) = k * 1
-2 * (4x + y) = - 2 * 1
-8x-2y = -2
Answer:
The property that justifies this manipulation is:
Multiply an equation by a scalar.
It is "Corresponding parts of a congruent triangle are congruent"
Hope this helps!
