Step-by-step explanation:
by-step explanation:
x: 13.8924439894498
y: 6
Step 2: x = 30 – 5
Step 3: x = 25
Part A: Is Charlie's solution correct or incorrect? If the solution is incorrect, explain why it is incorrect and show the correct steps to solve the equation. (6 points)
Part B: How many solutions will this equation have? (4 points)
Part A: Charlie's answer is incorrect. Part B: There is only 1 solution for this equation.
A linear equation is an equation that has the variable of the highest power of 1.
The standard form of a linear equation is of the form Ax + B = 0.
Charlie solved an equation;
Step 1: 5x = 30
Step 2: x = 30 – 5
Step 3: x = 25
Part A: Charlie's answer is incorrect.
In step 2 of Charlie's answer he subtracted 5 from each side. Since 5x is multiplication so, he must divide each side by 5 to get x by itself.
Step 1: 5x = 30
Step 2: x = 30/5
Step 3: x = 6
Part B: There is only 1 solution for this equation.

Answer:
x = -
Step-by-step explanation:
2 + + x =
Multiply through by 40 ( the LCM of 5 and 8 ) to clear the fractions
80 + 8x + 40x = 35
48x + 80 = 35 ( subtract 80 from both sides )
48x = - 45 ( divide both sides by 48 )
x = - = -
