The sum of their ages after 4 years = 56 According to given condition, ⇒ (5x+4) + (7x+4) = 56 ⇒ 5x + 7x + 4 + 4 = 56 ⇒ 12x + 8 = 56 ⇒ 12x = 56 - 8 ⇒ 12x = 48 ⇒ x = 48/12 ⇒ x = 4 The age of Roony = 5 × 4 = 20 years The age of Herald = 7× 4 = 28 years Practice Questions FAQs on Solve For x

WebTo check an answer to a system of equations containing x and y, enter the two equations separated by a semicolon, followed by the @ sign and an ordered pair containing your x-value and y-value. Example: x+y=7; … WebSo we have 5x plus 2y is equal to 20. If we want to solve for y, let's just get rid of the 5x on the left-hand side. So let's subtract 5x from both sides of this equation. The left-hand side, these guys cancel out, so we get 2y is equal to the right hand side, you have 20 minus 5x. And then you can divide both sides of this equation by 2.
