The value of "x" is
<em><u>Solution:</u></em>
Given f(x) = 4x - 6
g(x) = 8x + 4
<em><u>To find: value of x when f(x) = g(x)</u></em>
We can equate f(x) and g(x) as per given statement and solve for x
f(x) = g(x)
<em><u>Substituting the values of f(x) and g(x) in above expression,</u></em>
4x - 6 = 8x + 4
4x - 8x = 4 + 6
-4x = 10
On solving,
Thus value of "x" is
Answer:
x = 4
Step-by-step explanation:
-18 = -5x-(-2)
<h3>i) when there is a '-' sign in front of an expression in parentheses, change the sign of each term in the expression</h3>-18 = -5x+2
<h3>ii) move -5x to the left-hand side and change its sign</h3>5x-18 = 2
<h3>iii) move -18 to the right-hand side and change its sign</h3>5x = 2+18
<h3>iv) add the numbers</h3>5x = 20
<h3>v) divide both sides of the equation by 5</h3>
